INDIRECT-DRIVE MECHANISM FOR WINDING MACHINES.

Application filed July 11, 1923. Serial No. 650,953.

To all whom it may concern:

Be it known that I, CARL VETTER, a citizen of the United States, residing at North Andover, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Indirect-Drive Mechanism for Winding Machines, of which the following is a specification.

This invention has to do particularly with the delivery devices of tape condensers and of apron condensers. It may, however, be

used to advantage with any other textile machine in which a headed spool is driven by a drum, such as winding machines, ,spoolers and spinning mules whenever it is desirable to have adrum of less diameter than the spool heads. 7

In condensers of various types, it is considered desirable inthe United States practice to use spools having relatively large headson which to wind the roving as it is taken from the card.

Such heads protect the barrel while it is i being transported and help to hold the age from slipping off the ends.

On a tape condenser where there are four or more drums, each driving a spool, it is desirable to reduce the size of the drum so that the operator can reach between the drums from the back to care for the machine, as it is not convenient nor possible to reach in from the side. i V A spool with a ten-inchhead is in general use and it is usually necessary to drive it with a ten-inch drum, but with my device a 6%,} in. drum can drive aspool with a teninch head. This allows four inches extra space between the four drums.

With my preferred construction, I use a positive indirect drive in which all gears are protected and which can be adjusted for drums of different lengths,

In the drawings, Fig. 1 is a diagrammatic back View of the delivery end of a condenser with my device.

Fig. 2 is an enlarged side sectional elevation looking from the right of line 22 on Fig. 1.

Fig. 3 is an enlarged side sectional elevation looking from the right of line 3-3 on Fig. 1.

Fig, 4 is a sectional elevation of my slide packbracket, head and drum viewed from the left of Fig. 3.

Fig. 5 is an elevation of the slide bracket head from the opposite side to Fig. 3;

Fig. 6 is a view similar to Fig. 3 with part of the head broken away to show the.

interior.

Fig, 7 is a view similar to Fig. 3 of the bracket at the other end of the drum from the outside.

Figs. 8 and 9 are fragmentary views similar to Fig. 6 showing other driving mecha nism.

In the drawings, Fig. l is an elevation'of the delivery end of a tape condenser of'a common type having a frame indicated by N. As shown, there are four spool driving drums K, K, K, K, each of which is positively driven from any source of power as by means of a pulley P, and each of which drives frictionally a roving spool S.

In the construction shown, I provide for each set of spool and drum a supporting girtO which is fixed at each .end frame N' in a convenient position.

As is usual in such machines, there are for each spool two spool arms M, M each adjusta'bly supported'by a girt rod 0, each having the usual extension 11. for an extra empty spool, not shown, andthe spool supporting guides 10 and .12.which slope u 'wardly at. about a right anglewitheach other. Arms M are each carried by and adjustablejon a girt rod 0 by means of set screwssuch 7 Each spool S comprises a barrel 51 upon which the rovingis wound and which isin frictional contact with a drum K, two heads 52, 52, and bearing spindles 50 each of which restson a guideway 10 in a well'known manner.

Adjustably fixed to each girt O, preferto the bracket A which includes a tubular sleeve 28 slidable axially and revoluble in a guideway 15. It can be adjusted therein and fixed in position by means of a set screw a6.

This slide bracket may be cut away at 2'? to allow the head 52 of a spool to be slightly larger than would be otherwise possible, and has an axial bearing hole 26 for the drive shaft C on which is carried the drive pulley P.

Each drum K is, preferably, constructed with interior spiders 35 whereby it is carried by a drum shaft 32 which is no longer than the drum, I

One end of this drum shaft is carried by an arm 23 preferably integral with and forming part of slide bracket A which, preferably, carries a hub 22 in which is a hearing 21 therefor. 29 is an oil hole.

Its other end may be carried by another slide bracket T having a cylindrical shank similar in all respects to sleeve 28 except that it need not be tubular as there is no need of a drive shaft on this end. This slide bracket T has an arm 61 with, preferably, a hub 64: in which is a bearing 62 for the other end of drum shaft 32.

By means of the set screws 46 the position of slide brackets A and T can be adjusted so as to conform to drums of different lengths and also to swing up or down to the correct adjusted position with reference to the barrel of the spool S.

On the inside of drum K, at the driving side, I provide an internal gear 31 which is in mesh with a spur gear 30 carried by drive shaft C whereby the drum is positively driven.

Tokeep flyings from the gears and to avoidthe possibility of roving getting inside the drum, I prefer to provide each drum at each end with an internal annular groove 33 in which fits a head, such as H or 63, carried by and practically forming an integral part of the slide bracket arm 23 or 61. The drum revolves around these heads, which are so positioned that the centre of each is the centre of the drum shaft bearings, but do not support the drums, that function being performed by the. drum shaft 32 and arms 23 and 61. The outside of each head H and each arm 23 and 61 should be flush with the end of the drum and inside the spool heads.

I might use for my drive a spur bevel gear such as 7 O and internal bevel gear 71, as shown in Fig. 8, or a friction roller 7 3 in contact with the interior 74: of drum K I as shown in Fig. 9.

It is apparent that the protecting heads H and T, instead of being integral with arms 23 and 61, might be fastened thereto in many ways or might be omitted entirely.

It is to be understood that my device may be used in a machine in which the material on the spool is unwound as well as on one in which it is wound, and the expression textile winding machine in the claims is intended to include such an unwinding machine.
